Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Parts, position and numbering among the figure: damped cylinder magnetic valve 1, three position five-way valve 2, air gauge 3, two position three-way valve 4, preceding cylinder magnetic valve 5, pressure-reducing valve 6, back cylinder 7, damped cylinder 8, choke valve 9, damping oil pipeline 10, earthen pipe road, back 11, worker's inlet pipe road 12, preceding earthen pipe road 13, preceding cylinder 14, cylinder main shaft 15.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, cylinder 7, preceding cylinder 14, source of the gas and electric control system behind the utility model, source of the gas is connected on three position five-way valve 2 air inlets, preceding cylinder 14 links to each other with three position five-way valve 2 reverse action gas outlets by preceding earthen pipe road 13, back cylinder 7 links to each other with three position five-way valve 2 direct action gas outlets by earthen pipe road 11, back, and preceding earthen pipe road 13 is provided with preceding cylinder magnetic valve 5, back cylinder 7 is provided with worker's inlet pipe road 12 in addition and links to each other with three position five-way valve 2 reverse action gas outlets, and worker's inlet pipe road 12 is provided with two position three-way valve 4, pressure-reducing valve 6.At initial shape body, direct action gas outlet, the reverse action gas outlet of three position five-way valve 2 all keep connected state, preceding cylinder magnetic valve 5 also is in the connected state body, the equilibrium that keep-ups pressure of this moment back cylinder 7 and preceding cylinder 14, when the needs feeding, preceding cylinder magnetic valve 5 disconnects exhausts, and back cylinder 7 pressure of this moment are greater than preceding cylinder 14, thus the realization feeding.When the feeding of needs low pressure low speed, the direct action gas outlet of three position five-way valve 2 disconnects, be communicated with two position three-way valve 4, because pressure-reducing valve 6 effects, make that to enter the gas pressure of back cylinder 7 by worker's inlet pipe road 12 little, make that whole feed motion is steady, thereby reach the requirement of low pressure low speed feeding, when needs switch the high-voltage high-speed feeding, then use opposite method, two-position three way 4 not exhaust when disconnecting, its exhaust outlet are used for emergent exhaust and use.When needs retreat, if when being in the high-voltage high-speed feeding, the direct action steam vent that then is communicated with three position five-way valve 2, if when being in the feeding of low pressure low speed, then disconnect two position three-way valve 4 and together with the direct action steam vent of three position five-way valve 2, open preceding cylinder magnetic valve 5 and make preceding cylinders 14 be communicated with the reverse action gas outlet of three position five-way valves 2, at this moment preceding cylinder 14 pressure are greater than back cylinder 7, thereby realization retreats.In whole feeding and the process that retreats, all magnetic valves all have electric control system control, can realize above-mentioned action at an arbitrary position.In the time of in working order, if material hardness is big or load increases, then gas can compress, and air pressure increases, thereby reduces air inflow, and then reduces the depth of cut, and vice versa.
As shown in Figure 1, on worker's inlet pipe road 12, be provided with air gauge 3 between pressure-reducing valve 6 and the magnetic valve 4.Air pressure on worker's inlet pipe road 12 is through the air pressure after pressure-reducing valve 6 step-downs, at this moment, by air gauge 3 just can effectively observe measurement go to work the inlet pipe road 12 on air pressure, thereby help the control of air pressure.
On the basis of above technical measures, as shown in Figure 1, the feed system of deep hole machining also comprises damped cylinder 8, and cylinder links to each other by damping oil pipeline 10 with the back cylinder before the damped cylinder 8, damping oil pipeline 10 is provided with choke valve 9, and damped cylinder 8 main shafts and cylinder main shaft 15 are connected and fixed.Damped cylinder 8 comprises cylinder body, damping oil and is communicated with preceding cylinder and the pipeline of back cylinder, in the main shaft of damped cylinder 8 advances process, damping oil flows into the back cylinder by 10 the past of damping oil pipeline cylinder, because the existence of choke valve 9, damping oil can be hindered at choke valve 9 places, thereby realize providing the effect of resistance, in like manner, it also is like this flowing into preceding cylinder from the back cylinder.Damped cylinder 8 main shafts and cylinder 7 main shafts interconnect fixing, promptly two main shafts are done same movement, in the above-described embodiment, the adding of damped cylinder 8 will make feed system be subjected to resistance when transmitting motion, thereby effective must the buffering to motion, feasible motion is more steady, and can not cause the fluctuation of motion because of the fluctuation of gas atmosphere.
In the production process of reality, feed system usually requires to delay into rewind down, for this reason, on the basis of above technical measures, also is provided with the damped cylinder magnetic valve 1 in parallel with choke valve 9 on the damping oil pipeline 10.In needs fast feed with when retreating fast, be communicated with damped cylinder magnetic valve 1, damping oil just can transmit in the preceding cylinder of damped cylinder 8 and back cylinder fast by damping oil pipeline 10, and this moment, 8 of damped cylinders provided less resistance, thus realization F.F. or rewind down.When the needs work feed, disconnect damped cylinder magnetic valve 1 this moment, damping oil must enter the back cylinder by 9 the past of choke valve cylinder, thereby produces bigger resistance, makes that whole feeding process is steady, low pressure.
